Article Details
While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Main Article Content
Comparative genomics of spike, envelope, and nucleocapsid protein of severe acute respiratory syndrome coronavirus 2
Abstract
Background: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) upsurge sprang up in Wuhan, China, in late December 2019.
Objectives: Due to the exceptionally high mutation frequency, comparative genomics of viruses isolated throughout time and in various geographical locations are crucial. To better understand how SARS-CoV-2 heterogeneity has changed around the globe, this research was conducted.
Methods: Nucleotide and protein sequences of SARS-CoV-2, SARS-CoV, and bat SARS-like CoV were extracted from the NCBI Virus database. The Wuhan SARS-CoV-2 variant was used as a reference. Molecular Evolutionary Genetics Study performed the phylogenetic analysis, while the Genome Detective Coronavirus Typing Tool performed the mutational analysis.
Results: The evolutionary research has revealed that bats are the primary host for coronavirus evolution and the origin of the formation of SARS-CoV and SARS-CoV-2. Numerous mutations have been discovered in the spike, envelope, and nucleocapsid protein.
Conclusions: The current research findings may have an implication that facilitates the development of prospective immunization candidates/small pharmacological compounds targeting COVID-19.
Keywords: SARS-CoV-2; COVID-19; pandemic; comparative genomics; spike protein; envelope protein; nucleocapsid protein.
